Introduction to Solids LT-MAS DNP

Info:

This 4-day course is designed to give users an introduction to dynamic nuclear polarization (DNP) techniques and equipment. Users will gain hands-on experience operating low-temperature (LT) MAS probes as well as Bruker gyrotron microwave source. Additional topics include DNP sample preparation methods as well as tips for optimizing DNP performance. Upon completion of this course, users will be able to independently operate a Bruker DNP system.

Topics:

•  Introduction to DNP probes
  - LT-MAS and microwave component review
  - LT sample insertion and ejection
  - Rotor spin-up and spin-down procedures
  - Changing the RF configuration
• Operation of LT-MAS cabinet
  - Cool-down and warm-up procedures
  - Parameter control and monitoring via TopSpin
• DNP sample preparation
  - Polarizing and glassing agents
  - Preparation methods & rotor packing
  - Techniques for sample optimization
  - Biological vs. material sample preparation
• Gyrotron operation
  - Basic operation and maintenance
  - Microwave control parameters
  - Safety interlocks
  - Cross-polarized (CP) MAS DNP on standard samples
• NMR Field sweeping for DNP optimization
  - Measurement of DNP enhancements
  - Practices for safe field sweeping

Prerequisite:

This course requires graduate-level understanding of (and preferably hands-on experience with) MAS NMR techniques, including CP MAS experiments.

Equipment:

1. Gyrotron-based 400 MHz LT-MAS DNP system.
2. 3.2mm and 1.3 mm LT-MAS DNP probes.

Instructor: one PhD Applications Scientist.

This DNP training course is limited to 4 participants.
